2, 1 February 2000 | Radiology, Vol. 4, Seminars in Ultrasound, CT and MRI, Vol. Moreover, contrast-en-hanced abdominal CT scans obtained for a va - riety of indications typically include the lower portions of the chest. The journal Academic Emergency Medicine has published a study that looked at how often patients who go to US emergency departments (EDs) with chest symptoms of a pulmonary embolism (PE) get computed tomography (CT) scans, how often those patients are diagnosed with a PE, and how those numbers have changed over time. The Volume of IV contrast needed decreased by 40 % in group B compared to group A. MSCTPA using test bolus method reduces the amount of the contrast used with better opacification of the pulmonary artery and its sub segmental branches in addition to reduced artifact. If you’re a nurse practitioner who struggles with the same question, check out the following guide to contrast and CT scans. 9, American Journal of Roentgenology, Vol. , Radiology, 2010, vol. 6, No. Objectives: The purpose of this study was to compare the prognostic role of various computed tomography (CT) signs of right ventricular (RV) dysfunction, including 3-dimensional ventricular volume measurements, to predict adverse outcomes in patients with acute pulmonary embolism (PE). CT Venography. 23, No. 3, No. The study was carried out at the Warren Alpert Medical School of Brown University and Rhode Island Hospital, Providence, RI. Patients were excluded if CT scans could not complete due to allergic reactions to contrast medium and renal insufficiency, or suboptimal diagnostic image quality. 11, Magnetic Resonance in Medicine, Vol. PubMed 21. A pulmonary embolism (PE) is a blood clot in the lungs that has traveled from the deep veins of the leg or pelvis. To analyze the effect of the type of CT scanner (and its image reconstruction algorithm), information about the CT scanner on which the CTPA exam was performed was also recorded. 174, No. Anticoagulation is the main treatment for pulmonary embolism. doi: 10.1164/rccm.201310-1814LE … 20, No. Pulmonary embolism (PE) is a common condition with high mortality and morbidity. 41, No. 1, European Journal of Nuclear Medicine, Vol. Left undiagnosed and untreated, about one-third of cases of pulmonary embolism result in death. 2, Progress in Cardiovascular Diseases, Vol. MATERIALS AND METHODS: Sixty patients suspected of having PE were prospectively evaluated with pulmonary angiography and contrast-enhanced electron-beam CT. Thirty-eight patients underwent ventilation-perfusion (V-P also … Pulmonary embolism at CT angiography: implications for appropriateness, cost, and radiation exposure in 2003 patients. If the address matches an existing account you will receive an email with instructions to reset your password. Prospective evaluation of unsuspected pulmonary embolism on contrast enhanced multidetector CT (MDCT) scanning. Title: Pulmonary embolism: incidental finding in routine outpatient CT scans The aim of the study: to evaluate CT diagnostic possibilities while diagnosing incidental pulmonary artery embolism in routine CT scans. There are several contrast agents that may be used in performing CT scans. Imaging of acute pulmonary thromboembolism: should spiral computed tomography replace the ventilation–perfusion scan? 2 doctor answers. 2, The Japanese Journal of Thoracic and Cardiovascular Surgery, Vol. Background: Three-dimensional ventricular volume measurements based on chest CT have become … Once the time to peak is determined (ex. A chest CT scan also can help determine the cause of lung symptoms such as shortness of breath or chest pain, or check to see if you have certain lung problems such as a tumor, excess fluid around the lungs that is known as pleural effusion, pulmonary … 5, Clinics in Chest Medicine, Vol. 3, Current Problems in Diagnostic Radiology, Vol. 2, 1 January 2000 | Magnetic Resonance in Medicine, Vol. 8, Journal of Computer Assisted Tomography, Vol. 5, Baillière's Clinical Obstetrics and Gynaecology, Vol. Conclusion: PE-CADx correctly identified 77.4% of cases of acute PE that were previously missed in clinical practice. Ventilation-perfusion lung scanning and spiral computed tomography of the lungs: Competing or complementary modalities? 12, The American Journal of Cardiology, Vol. 32, No. 26, No. Patients were referred by physicians for CT scans with the aim of detecting and diagnosing pulmonary embolism.
